寿山“芙蓉石”的谱学特征研究

Study on the Spectral Characteristics of"Ross Quartz"from Shoushan

福建寿山石因质地晶莹剔透、凝脂如玉、色彩多样,在国内外享誉盛名。采用常规宝石学测试法、红外光谱仪、紫外-可见分光光仪、拉曼光谱仪、电子探针等仪器对寿山“芙蓉石”的谱学特征进行了系统的研究。红外光谱与拉曼光谱测试数据表明寿山芙蓉石的主要矿物成分为叶蜡石,其中红外光谱尖峰主要在1132 cm^(-1)、1077 cm^(-1)、946 cm^(-1)、1015 cm^(-1)、470 cm^(-1)、429 cm^(-1)附近,拉曼特征尖峰在127 cm^(-1)、267 cm^(-1)、334 cm^(-1)、432 cm^(-1)、481 cm^(-1)附近;能谱扫描数据和紫外可见光谱测试结果显示褐红色部分颜色的主要致色离子为S和Pb。

Fujian larderite is famous at home and abroad because of its crystal texture,condensed fat such as jade and diverse colors.This paper investigates the spectral characteristics of“ross quartz”from Shoushan County,Fujian Province by using EPMA,FTIR,Raman spectrometer and UV-Vis-NIR spectrometer.Their infrared spectra and Raman spectra are the same as those of pyrophyllite:the infrared spectrum characteristic peaks are located at 132 cm^(-1)、1077 cm^(-1)、946 cm^(-1)、1015 cm^(-1)、470 cm^(-1)、429 cm^(-1),and the Raman characteristic peaks are concentrated at 127 cm^(-1)、267 cm^(-1)、334 cm^(-1)、432 cm^(-1)、481cm^(-1).Combined with the results of EPMA,UV-Vis absorption spectrum test,the results showed that the color of“ross quartz”from Shoushan County,Fujian Province is related to the content of S and Pb.
